GPM SKM153 Kyosho Motorcycle Steel Middle Gear  [SKM153]

Steel middle gear for Kyosho motorcycle drivetrains

This steel middle gear is an aftermarket RC-scale replacement supplied as a single 1pc item and intended for use with Kyosho motorcycle models. It functions as the central gear stage inside the bike gearbox, transferring torque from the motor pinion to the spur set.

Manufactured from steel to resist wear better than common plastic options, this part is suited to running where longevity and consistent mesh are priorities during normal use or light tuning. Note that this is a single drivetrain gear, not a complete gearbox assembly.

Installation notes: inspect shaft alignment and bearing condition before fitting, set correct gear mesh against your existing pinion and spur, and avoid excessive bearing preload. Use standard RC tools and rotate the assembly through full suspension travel to confirm smooth operation and no binding.
